It's a taylor basic kit, DPD
Phenol red for PH.

used 5 gallons 'Great Value' sodium hypo (8.25%) last night put me at 10ppm this morning (was 2 at a 1 to 5 ratio) so I figure I'll try half as much tonight to get it to 15 (I test again at dusk to see if I lost much, with this high CYA i don't think i will).

gonna grab some distilled water today for a better PH reading
